Abstract
The utility model discloses a direct-current brushless motor control circuit for an aerator. The circuit comprises a system power management module, a gate driving module and a DSP control module which are coupled together; and a motor which is coupled with the gate driving module and the DSP control module. The direct-current brushless motor control circuit further comprises a rectification module which is coupled with the system power management module. The rectification module is connected with an external alternating-current power supply. According to the utility model, the conventional direct-current motor control system is mainly composed of a DSP control module and an intelligent power module, and the control circuit provided by the utility model is additionally provided with the rectification module, such that the system can use a 220V alternating-current power supply directly, and after the rectification and filtering of the rectification module, a 315V direct-current voltage is obtained.
Description
Technical field
The utility model relates to the improvement of DC brushless motor controller, particularly a kind of Brush-Less DC motor control circuit for aerator.
Background technology
The controller that the dc brushless motor that original aerator is used uses must use DC power supply.There is defective:
1, the controller that uses of the dc brushless motor used of former aerator must use DC power supply, and aerator is multiplex in culture fishery, once the DC power supply electric weight is inadequate, the motor of aerator can quit work, aerator is corresponding can not oxygen supply, can cause a large amount of losses to the raiser.
2, aquaculture generally out of doors, when using storage battery power supply, the management of battery is extremely constant, charging is also inconvenient.
The utility model content
The utility model provides a kind of high power DC brushless electric machine control circuit that can directly use the alternating current of 220V.
For solving the problems of the technologies described above, the utility model is used for the Brush-Less DC motor control circuit of aerator, comprising: the power supply managing module, grid electrode drive module and the DSP control module that intercouple and connect; Motor, described motor and described grid electrode drive module and described DSP control module are of coupled connections; Described Brush-Less DC motor control circuit for aerator also comprises rectification module, and described rectification module and described power supply managing module are of coupled connections.Described rectification module external AC power supply.
The Brush-Less DC motor control circuit that the utility model is used for aerator is mainly to be to be made of DSP control module and two parts of Intelligent Power Module in original DC motor control system, now adding rectification module. system can directly use the 220V Alternating Current Power Supply, behind the rectification module rectifying and wave-filtering, obtain approximately 315V direct voltage.
Description of drawings
Fig. 1 is the Brush-Less DC motor control circuit block diagram that the utility model is used for aerator.
Embodiment
Below in conjunction with accompanying drawing the Brush-Less DC motor control circuit that the utility model is used for aerator is described in further detail.
As shown in Figure 1, the utility model is used for the Brush-Less DC motor control circuit of aerator, comprising: the power supply managing module, grid electrode drive module and the DSP control module that intercouple and connect; Motor, motor and grid electrode drive module and DSP control module are of coupled connections; The Brush-Less DC motor control circuit that is used for aerator also comprises rectification module, and rectification module and power supply managing module are of coupled connections.The rectification module external AC power supply.
The Brush-Less DC motor control circuit that the utility model is used for aerator is mainly to be to be made of DSP control module and two parts of Intelligent Power Module in original DC MOTOR CONTROL system processed, now adding rectification module. system can directly use the 220V Alternating Current Power Supply, behind the rectification module rectifying and wave-filtering, obtain approximately 315V direct voltage.
The Brush-Less DC motor control circuit that the utility model is used for aerator is partly to increase a step-up transformer at original controller power source, like this external power supply low-voltage input, through behind the step-up transformer, the required electric current that bears of controller has just reduced, and the manufacturing cost of controller reduces.
The preferred embodiment of below the utility model having been created specifies, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
